Why can't I have two animations in one objects when using property play mode?
The attached BLEND file shows how this is accomplished.
The trick is to use three different actions added each to their own "NLA" tracks.

It's set up to use the GE, so use keys A, S, &amp; D to control animation #1, #2, &amp; #3 (#3 = #1 &amp; #2 together).
